Brain Stem & Cerebellum Injuries

Brain Stem

The brain stem (base of the brain) is located near bony protrusions that make it vulnerable to damage during trauma. The brain stem serves to provide the individual with basic attention, arousal and consciousness. The brain stem connects the brain to the body and performs basic survival functions such as breathing and heart rate.

When trauma causes brain swelling, fluid pushes up against the skull and can cause the brain to push down on the brain stem. This compression of the brain stem can damage the part of the brain that is responsible for consciousness.

Signs and symptoms associated with a brain stem injury include:

Altered heart rate

Loss of consciousness

Abnormal breathing patterns

Inability to control movement

Inability to cough or gag

Abnormal sleeping patterns

Cerebellum

The cerebellum is located at the bottom of the skull near the opening to the spinal cord. It is divided into two hemispheres by the central “vermis.”

The cerebellum coordinates movement, planning, motor activities, physical skills and some cognitive abilities. It collects sensory nerve inputs, such as vision, balance information and limb position, and synthesizes them to control movement. Cerebellar memory stores information from trial and error of physical tasks, e.g., riding a bike. The primary function of the cerebellum is to coordinate the timing and force of muscular contractions so that body movements are appropriate for the intended task.

Loss of balance and vertigo (resulting in shuffling walk and a wide stance)

Loss of muscle or posture tone, or muscle weakness

Dysarthria (loss of coordination of the muscles controlling speech)

Deficit in verbal working memory

Slow or slurred speech

Many times it is difficult to diagnose what part of the brain is injured. Neuropsychology is the study of the relationship between the brain and behavior. Neuropsychologists perform tests to evaluate cognitive function and emotional status in order to identify problems which can then be linked to a physical cause. A neuropsychological evaluation (NPE) includes a series of assessments ranging from standard IQ tests, to personality tests, to fine motor control evaluation, all of which usually takes several hours.
